Written by Blake and his wife Miranda Lambert, the touching song is about the loss of Blake’s brother, who was killed in a car accident when Blake was a teenager. “Over You” was recorded by Miranda and released on her album Four the Record, and it hit Number One last year on the country singles charts.

As Blake explains to Radio.com, “Over You” is a song he and Miranda wrote “because we were talking about my brother. And that’s how those things should happen, probably. It was really a way of healing, and honoring my brother’s memory.”

Blake tells Radio.com, though, that the initial idea for the song actually came from a comment his father made.
